SDN (Software Defined Networking) is a networking architecture that uses software to control network traffic instead of traditional hardware-based systems.
SDN was first introduced by a group of researchers from Stanford University in 2005.
In 2011, the Open Networking Foundation (ONF) was formed to develop and promote SDN standards and technologies.
Since then, many companies have adopted SDN, and it has become a popular networking technology.
Cisco is a multinational technology conglomerate that produces networking hardware and software.
VMware is a software company that provides virtualization and cloud computing products and services.
Juniper Networks is a multinational corporation that develops and markets networking products and services.
OpenFlow is a standard protocol used to communicate between the controller and the switch in an SDN architecture.
Network virtualization allows for multiple virtual networks to be created on top of a physical network infrastructure.
SD-WAN (Software Defined Wide Area Networking) is an SDN technology that is used to connect and manage multiple remote networks.
